Chapter 11. CREATING DYNAMIC GRAPHS IN Z... > Dynamic Graphs of the Poll Product

Dynamic Graphs of the Poll Product

In Chapter 8, “Creating Polls and Surveys,” we worked with the Poll product to get the portal members' opinions about the portal. This product supports dynamic graphs to better represent the Poll votes. Without PIL being correctly installed in your Zope version, the parts of the Poll product that produce the graphs are ignored.

Now that PIL is installed on your machine, the graph should automatically show when you go to either the results page or the Edit view of a Poll instance. However, due to a problem within the Poll product, this is not the case. Instead, you will see a broken image where there should be the graph.
